Lightsaber Staff Quick-Release.

Hi, I’ll try to make this as succinct as possible. I have recently been looking for lightsabers but I am new in the market and I don’t have the best idea of where and what to look for. I really want either a quick release Sabre-staff or two lightsabers with that ability to combine into a Sabre-staff. Also I have heard that ultra sabres is very unethical and has many problems, but i cant find any other place to get a quick release binding. Thank you for your time and if you could help me that would be amazing! Thank you.
